HOTTER WATER CAN SCALD: Water heaters are intended
to produce hot water. Water heated to a temperature
which
wilt satisfy clothes washing, dish washing, and other sanitizing
needs can scald and permanently
injure you upon contact.
Some people are more likely to be permanently
injured by
hot water than others. These include the elderly, children, the
infirm, or physically/mentally
handicapped.
If anyone using hot
water in your home fits into one of these groups or if there is a
local code or state taw requiring a certain temperature water at
the hot water tap, then you must take special precautions.
In
addition to using the lowest possible temperature
setting that
satisfies your hot water needs, a means such as a mixing valve
should be used at the hot water taps used by these people or
at the water heater. Mixing valves are available
at plumbing
supply or hardware stores. Follow manufacturers
instructions
for installation of the valves. Before changing the factory setting
on the thermostat,
read the "Temperature Regulation" section
in this manual.
See Figure 7 for mixing valve usage.

FIGURE 7.
The water supply pressure should not exceed 80 psi. If this
occurs, a pressure
reducing valve with a bypass should be
installed in the cold water inlet line. This should be placed on
the supply to the entire house in order to maintain equal hot and
cold water pressures.
Figure 8 shows the attachment
of the water
piping to the
water heater. The water heater is equipped with 3/4" water
connections.
If a water heater is installed in a closed water supply system;
such as one having a back-flow preventer, check valve, water
meter with a check valve, etc.., in the cold water supply; an
expansion
tank or other means must be provided to control
thermal expansion.
Contact the local utility or Sears Service
Center on how to control this situation.
NOTE: If using copper tubing, solder tubing to an adapter
before attaching the adapter to the water inlet connection.
Do not solder the water supply lines directly to the cold
water inlet. It will harm the dip tube and damage the tank.
